Description

The properties of the effect observed in formation in the reaction anti-pp→π+π-π+π-π0 at 1949+-10 MeV/c2 (GAMMA approximately 80 MeV/c2) are studied. The ω0rho0, A20 π+π- and π+π-π+π-π0 (non-resonant) channels are found to be coupled with this object. The assignment Isup(G)=1- is established and an analysis of the √s behavior of the density matrix elements for the final state ω0rho0 clearly favours Jsup(P)=2+, 4+ ... Comparisons are made with present theoretical schemes describing this mass region
